The moment he ate the ball, he felt it lose form in his mouth, quickly spreading out and giving a strong iron taste, just like blood. He didn't wait in swallowing so as to make full use of his future vision.
In the first second, he felt an instinctual rejection from it. This gave him a bad feeling.
By the next second, he felt this blood directly enter his bloodstream somehow, almost like it was alive. Whatever it was, it made him feel like parasites had entered his body.
At the third second, he could tell that the black blood was actively trying to attack his body like it wanted to seize control. His body tensed up automatically and began instinctively fighting against this force.
Ew, stop farting Nyoka! I can see it from here....
